I wouldn't count on cell coverage. the normal caveats about riding alone aside, its not a real tough trail if you are an experienced AZ rider. About 14 miles\2 hrs, some decent climbs at elevation , but nothing gnarly and nothing real long or painful. If you ride any of the rugged trails around here alone, you should be ok. No services, so have enough water.bobo_krkk_NIN said:
You might see some folks, but dont count on it. Its not remote, but remote enough if you get into trouble 20 min off the road.
Biggest risk might be getting lost, as there are options and it can be easy to lose direction in the trees. Bring a gps etc to be safe and a map hardcopy, esp. if alone on a new trail.
